The Muncie A20-A1006-HX5IIBX or A20A1006HX5IIBX is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, giving installers flexibility in tight mounting situations, and the rotatable pump flange adds further layout options. Extended-length PTO mounting fasteners and increased housing clearance simplify installation. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while the maximized gear geometry keeps operating noise down. The A20 Series uses a single intermittent/continuous torque rating and is offered in three housing arrangements. This unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission -- call us to confirm the right configuration for your application.
